"This Lisa emulator tries to give you the full experience of using an Apple Lisa. The backdrop is a photo of a Lisa that changes as the power light comes on and when you 'insert' a disk. It even plays the sound of the Lisa disk drive running as you access the disk. To start the emulator you must press the 'Power button' just as you would start a real Lisa."
